Python | Django
I'm a complete noob to programming and currently learning python and django. Recently, I created a python application that requires an input (string) from a user in order to provide desired output. It works perfectly however I would like to make it into a django app where I can provide a gui for inputing the string. python app downloads images to a user machine so I am not worried about the displaying of output. I've been following some tutorials on building and adding applications to django and I kind of understand how it works however I am not sure how to tackle adding an existing application and providing a gui or "input" field for the python application which I already built. Any kind of guidance will be appreciated. thanks -
How to limit the number of records in the Serializer
Hello everyone, how to limit the number of results using a serializer? In short, there is a table of comments, which can contain different types of posts. class CourseComment(models.Model): user = models.ForeignKey(User, on_delete=models.PROTECT) content = models.TextField() content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE) object_id = models.PositiveIntegerField() content_object = GenericForeignKey('content_type', 'object_id') created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) and here related table class CourseMessage(models.Model): course_id = models.ForeignKey(Course, on_delete=models.PROTECT) author_id = models.ForeignKey(User, on_delete=models.PROTECT) text = models.TextField() # RAW Format must exclude specials chars before publish is_pinned = models.BooleanField(default=False) comments = GenericRelation('CourseComment') created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) I made the serializer according to the documentation https://www.django-rest-framework.org/api-guide/relations/ class CourseMessages(serializers.ModelSerializer): user = Author(source='authorid', read_only=True) files = MessageFiles(source='coursemessageattachedfile_set', many=True) message_comments = MessageComments(source='comments', many=True, read_only=True) class Meta: model = CourseMessage fields = ['text', 'updated_at', 'user', 'files', 'message_comments'] class MessageComments(serializers.RelatedField): def to_representation(self, value): ct = ContentType.objects.get_for_model(value) serializer = Comments(value, read_only=True, source='last_comments') return serializer.data class Comments(serializers.ModelSerializer): author = Author(source='user', read_only=True) class Meta: model = CourseComment fields = ['content', 'author'] Everything works well, but I would like to see first 3 comments.

Querying using related field names
I've got two models that I'd like to perform a reverse search on. I'm wondering how to do this given the fact that one model has to fields with foreign keys to the same model. class Review(models.Model): cart = models.ForeignKey(Cart, on_delete=models.CASCADE, default=None) class Job(models.Model): cart = models.ForeignKey(Cart, related_name="cart_one", on_delete=models.CASCADE, null=True, blank=True) unscheduled_job = models.ForeignKey(Cart, related_name="cart_two", on_delete=models.CASCADE, null=True, blank=True) employee = models.ForeignKey(Employee, on_delete=models.CASCADE, null=True, blank=True) My query is as follows: reviews = Review.objects.filter(cart__job__employee=employee) This query is failing due to the fact that the Job model has two foreign keys that point to the cart model. How would I fix this? Thanks! -

Read with pandas once and keep many csv files open or read and close each time
I am doing a project with Django in which I generate several graphs with Plotly and do operations with CSV files that I read, write and modify (also download or delete) with pandas. These files depend on the company to which the user belongs, for example, if it belongs to the TOYOTA company, the file is in data / toyota, and if it belongs to Honda, it is in data / honda. My question is which is better, to read the 50 csvs that will be used when the user logs in, or to read and close the csvs as needed. For example, in my url example.com/analysis, these functions are called: @login_required def analysis(request): data_report = pd.read_csv(f'data/{request.user.company}/test/data_report.csv', sep=';', encoding='utf-8') context = {} for column in data_report.columns: context[column] = data_report.loc[0, column] data_roles = pd.read_csv(f'data/{request.user.company}/test/data_roles.csv', sep=';', encoding='utf-8') # Here more code that doesn't matter ... graphs = [] marker = { 'color': 'rgb(0,150,209)', 'opacity': 0.5, } graphs.append( go.Scatter(x=n_users, y=n_perms, mode='markers', name='Line y1', marker=marker) ) layout = { 'xaxis_title': 'Number of users', 'yaxis_title': 'Number of permissions', 'height': 400, } plot_div = plot({'data': graphs, 'layout': layout}, output_type='div') context['plot_div'] = plot_div return render(request, 'analysis.html', context) @method_decorator(csrf_exempt) def update_pie_chart(request): if request.method == 'POST' and request.is_ajax(): selected … -

I am using JSONWebTokenAuthentication This is the implementation: class vistaUsuarios(APIView): permission_classes = (IsAuthenticated,) def usuario(request): print("USUARIO ",request.user.is_authenticated) if request.method == 'GET': usuario = None id = request.GET.get("id") if id is not None: usuario = Usuario.objects.get(pk=id) usuarios_serializer = UsuarioSerializer(usuario) return JsonResponse(usuarios_serializer.data, safe=False) settings.py REST_FRAMEWORK = { 'DEFAULT_PERMISSION_CLASSES': ( 'rest_framework.permissions.IsAuthenticated', ), 'DEFAULT_AUTHENTICATION_CLASSES': ( 'rest_framework_jwt.authentication.JSONWebTokenAuthentication', 'rest_framework.authentication.SessionAuthentication', 'rest_framework.authentication.BasicAuthentication', ), 'NON_FIELD_ERRORS_KEY': 'global', } # JWT settings JWT_AUTH = { 'JWT_ALLOW_REFRESH': True, 'JWT_EXPIRATION_DELTA': timedelta(days=2), } # allauth SITE_ID = 1 ACCOUNT_EMAIL_VERIFICATION = 'none' # JWT settings REST_USE_JWT = True INSTALLED_APPS = [ 'corsheaders', 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'rest_framework', 'subroutinesbackapp', 'django.contrib.sites', 'allauth', 'allauth.account', 'rest_auth', 'rest_auth.registration' ] ... The problem is that IsAuthenticated is never executed. I have a print there, and never do. class IsAuthenticated(BasePermission): """ Allows access only to authenticated users. """ def has_permission(self, request, view): print("holaaaaaaa") return bool(request.user and request.user.is_authenticated) The method usuario from vistaUsuarios class, always execute. Even though the print print("USUARIO ",request.user.is_authenticated) shows USUARIO false because I haven't passed a valid token. How can I make the IsAuthenticated method execute? Thanks, in advance -
